If you define an earthquake as generation and sperading of seismic waves and related strong ground motion, the answer is certainly yes:

Every surface or subsurface explosion (such as bunker busters) will cause earthquakes (for example: https://en.wikipedia.org/wiki/Earthquake_bomb ). Air explosions may also cause earthquakes, but they will have less intensity due to dynamic impedance mismatch. Sub-surface nuclear test also cause strong ground motions, actually they are detected with special seismic networks.

If you define an earthquake as the sudden release of energy from Earth's crust from tectonic activity: The answer is also yes, because human activity such as dam construction, shale gas drilling etc is known to induce seismic activity but I haven't stumble upon papers on bombing induced seismicity yet.

Good luck!

A big meteor fall would be comparable to bombing and that would cause a quake.

The Chelyabinsk meteor blast (not fall) in 2013 caused a magnitude 2.7 while the bigger Tunguska blast up to a magnitude 5. A suspected meteor fall near Norway House,  (Canada) caused a magnitude 4.

Yes, there within seismic zone, some seismogenic stress are accmulated in the subsurface as a track. If explosion of heavy boam in this zone earthquake will be cause.

Simply put, yes.  However, the energy should not radiate as a double couple, the first arrival should be compressional in every quadrant if it is a bomb.

As others have explained, the bombing creates seismic waves. But here I would like to emphasize that unless the bombing is nuclear, the magnitude is really small and wont be felt far away. Even detecting it with broad band seismometers will be a problem due to sources of noise and low signal to noise ratio. If you have nuclear explosion at the surface, then you will get higher magnitude near the blast site, but the attenuation will be much higher due to loss of part of energy to the atmosphere. Underground nuclear explosions have magnitudes between 4 ~ 5 Mw, but it depends on the weight and type of payload. Normally, when refered to earthquake, no man-made weapon can cause an earthquake as big as 6 Mw or higher because you will need thousands if not millions of tons nuclear fissile material ( https://en.m.wikipedia.org/wiki/Richter_magnitude_scale ). Also, no weapon can trigger a fault, so that fault cause an earthquake in turn.

 Yes, of course. It can be look as earthquake

Yes. In seismic surveys, explosions are induced into the earth to generate seismic waves which travel and  are recorded at some other points away from the disturbance point. Same principle applies too during bomb explosions. The explosions actually generate seismic waves, which means they cause earthquake but of small magnitudes that make them not to be felt. 

Never an earthquake you might feel but at the megaton level, quite possibly.

Cause is the wrong word here. Trigger is the more appropriate verb to use. In my view it is improbable that heavy bombing will trigger any earthquake of significant magnitude, especially in aseismic regions of the Earth. That said, a large underground nuclear explosion may trigger moderate-sized earthquakes in tectonically active regions like the Nevada Nuclear Test Site in the US.

Yes, heavy bombing may trigger earthquakes especially in seismic active areas. Such strikes may activate certain existing stress patterns in the area that may lead to an earthquake.

Heavy bombing (using conventional weapons) can in no way trigger local seismic activities remotely comparable to those by moderately large underground nuclear weapons tests (tens of KT equivalent of TNT). In terms of destructiveness, nothing of consequence would likely arise from triggered earthquakes associated with aerial bombing. If the question pertains to DPRK, the answer is even more straightforward: the northern part of Korean Peninsula is largely aseismic, and the region surrounding Chik-Tong Nuclear Test Site is particularly aseismic.
